Method and Device for Determining Reference Signal, Method and Device for Determining Control Channel Unit, and Storage Medium

3. The method of claim 2, wherein a short TTI where a first traffic transmission for activating the SPS transmission is performed comprises the reference signal.

5. The method of claim 4, wherein a short TTI where a first traffic transmission for activating the SPS transmission is performed comprises the reference signal.

6. The method of claim 1, wherein among each N short TTIs, the reference signal is comprised in a first orthogonal frequency division multiplexing (OFDM) symbol in a short TTI comprising the reference signal.

7. The method of claim 1, wherein a short TTI where a first traffic transmission for activating the SPS transmission is performed comprises the reference signal.

8. The method of claim 1, wherein the signaling has different meanings for an SPS period of one short TTI and for other periods, wherein the signaling is valid for the SPS period of one short TTI and is used for a reference signal indication in the each N short TTIs, and the signaling is used for a reference signal indication in a single short TTI for the other SPS periods.

9. The method of claim 1, wherein the method is applied to SPS with a period of one short TTI.

10. A non-transitory storage medium, comprising stored programs, wherein, when executed, the programs execute the method of claim 1.

15. A non-transitory storage medium, comprising stored programs, wherein, when executed, the programs execute the method of claim 11.
